Threat of Tuesday Moderate Snow Event for PA & Surrounding Areas Growing

Potential of Tuesday Plowable Snow Growing, Too Early For Amounts

        The title of this update is great news to some and frustrating to others, especially those in Southern PA who are finally seeing grass after almost two weeks. To begin with, you all need to understand that this update will not tell you snowfall amounts or who will see the most, that info will be addressed in the coming days!

        Things may get a little technical but most of you will get the overall idea. What we will be looking at is an Alberta Clipper diving down from Canada into the Lake Erie region. A secondary low pressure will then form in the Western Virginia region, which will strengthen as the original primary low pressure over Lake Erie transfers its energy to the secondary.

        The secondary low pressure will then head east through Virginia before it moves northeast off the coast. This is an ideal setup for some areas of the state to receive a moderate snowfall, especially the Eastern Half. It really depends on where the secondary low pressure develops and how fast it strengthens.

        We realize that we are practically one of the only weather sources addressing this threat. However, by Friday and Saturday you can expect just about everyone to hop on-board if models continue to increase this potential. The map below illustrates the POTENTIAL and does not include any amounts.

        Our first look forecast will come tomorrow evening, no amounts will be forecasted but we will take a look at what areas could see the biggest impacts from this potential storm!

Hello, my name is Josh Adams. This year I am a junior in high school in South Central PA. I have had a passion for weather since I was five or six years old, watching the Weather Channel when the average kid my age was watching cartoons. At age 11, I discovered that there is a significant amount of weather info online from knowledgeable meteorologists to weather models and everything in between. I had the privilege to take part in a group that held informational weather discussions nearly everyday. I gained a significant amount of knowledge in several months back in 2012, constantly studying meteorology for hours each and just about every day. I created Northeast Weather Action in early 2013, just after the previous winter had ended. Things were pretty slow to start, however the winter of 2013-2014 greatly helped grow the page. Several of my forecasts verified nicely across the area. I met Chris during that winter in a facebook group, and we talked often about anticipated weather events. Just before the start of the 2014-2015 Winter, I added Chris to Northeast Weather Action (now Pennsylvania Weather Action), and once again we hit several key forecasts. Chris and I are looking forward to giving you the most up to date and reliable forecasts!
